How do I fix .PSD file association?

I just wanted to know how could I fix the file association of Photoshop *.PSD file. I've got Photoshop CS5 installed, and I can open the file with it, but the thing is the icon is messed up. It's basically a white paper with the Photoshop "PS" icon in the center, which is messed up according to me, cause on my other computer, the icon of the .PSD file is a complete blue icon with PSD label on the right top corner. I wanted to know if there was a way for me to fix this icon issue. I'd be grateful for any help provided.

First thing to try is to right click on the icon and choose properties> shortcut> change icon. See if the icon you want is available there. If it isn't, browse the Photoshop program folder to see if it available there.
